Using of postharvest treatments in citrus fruit is important due to maintaining of antioxidant compounds during cold storage. In this study, Thomson and Moro fruits after coating (Polyethylene, Shine, Storage and Britex Ti waxes, Polyethylene pack, Tecto 60 fungicide and Control) were stored for three months in cold storage (5°C, 85 RH). Antioxidant compounds changes were evaluated with sampling each 30 days interval. The results showed total phenolics increased during 30 days of storage and then decreased, significantly. Pulp phenolics in both cultivars increased using Polyethylene pack and Storage wax than other treatments. Peel tissues of Moro variety which treated by Polyethylene, Shine and Storage waxes had higher levels of total carotenoid in the second month of storage. Thomson fruits that covered with Shine and Storage waxes had the highest and the lowest ascorbic acid, respectively. The amount of ascorbic acid in Moro fruits covered with Britex Ti decreased during storage. In the end of storage, just fruits coated by Shine wax had higher total anthocyanin, significantly. Based on the total antioxidant capacity, it was found that fruits treated with Storage, Britex Ti waxes, and Polyethylene pack had higher inner quality and antiradical potential during storage.
